Description

The present invention relates to a heater used to heat the liquid in a PET bottle.

In the event of a disaster such as an earthquake, in the electrical field, it is first required to secure the lighting of the facility that will be the evacuation center, but that facility is not a one-night evacuation center, but a place of continuous living. In that case, it should be possible to meet the demands of making milk for infants, eating warm foods, and keeping warm.
However, the external power supply that can be used when the supply of commercial power is cut off in the event of a disaster is limited, and while the minimum amount of hot water required to make milk can be provided, the others can be provided with cold lunch boxes and sweet buns. Or provide a blanket at best.
